I've purchased these strings partly out of curiosity. I play the acoustic a lot, mostly using the metal finger picks, and needless to say, that kind of abuse would wear out any strings pretty quickly. Usually, I would just buy more expensive strings, not even thinking about trying out the cheaper ones, because mostly my experience with the cheap strings were bad, but then I've stumbled on these when browsing here on Thomann. I've thought to myself; hell, why not give them a go, they are cheap so there's nothing to lose. After trying them on, I must say I was very pleased. The sound was bright and definitely a considerable and important improvement when compared with the used strings, and after about a month of usage they still didn't break, and that's what I really wanted. I haven't bought them expecting miracles, just wanted strings that will sound fresh and won't break easily, so the home practice and playing would be more enjoyable, and that's exactly what I've got. I would rather put these on my guitar once per week, and that would still be cheaper than one pair of the more expensive strings I would usually put on, which would soon wear out and then I would play on these worn out and dull strings for a month or more, before a new change.
That being said, in the case of recording or live performance, I would still go with the more expensive strings, like perhaps D'Addario or DRs, but for the purpose I've intended it these work out just fine, and when I take the price in the consideration, I feel it would be unjust of me to give them any less than the highest score.
